Comparison of Solubility, Water sorption and Marginal leakage between XenoCem-plus Resin Cement (Dentsplysankin, Japan) and GI Fuji I cement (GC,Japan).

摘要

Fixed prosthesis treatments have a very important role in replacing lost portion of/or extracted teeth. Although the long- term clinical success of this treatments require to have a restoration with desirable features such as retention, stability, preservation of tooth structure, structural durability, marginal integrity and preservation of periodontium, but it is dependent to cement . 32 sound human maxillary premolar teeth were selected, which were not passed over three months from their extraction due to orthodontic treatments. The mean of dye penetration in buccal (A) and lingual surface (B) and the overall mean of dye penetration in two kinds of cements were respectively 0.23, 0.22 and 0.225 mm in GI cement and 0.22, 0.24 and 0.23 mm in Xeno cement. In addition, mean of standard deviations of dye penetration inbuccal and lingual surface and overall mean of dye penetration in two kinds of cements were respectively 0.191, 0.139 and 0.163 in GI cement and 0.141, 0.176 and 0.155 in Xeno cement. The most dye penetration between studied samples was 0.55 mm that it was in buccal surface of GI cement and the lowest dye penetration was 0 mm that it was seenin both cements. In negative control group, was not found dye penetration in samples. There was statistically significant difference between the main groups and positive control group (p 0.05). In this study have been compared amount of marginal leakage, percent of solubility and water sorption in two kinds of GI Fuji I and Xenocem-plus luting cement. The main group cemented veneers marginal leakage in both kinds of cements was not significant differencesand both cements for leakage were almost identical. There were statistically significant difference between the main groups and control samples, so that amount of marginal leakage was significantly higher in control groups. In all intervals, the solubility of Xenocem-plus resin cement was lower than GI cement. Therefore, according to the conditions and limitations of this study, Xenocem-plus resin cement has preference to GI cement. In all intervals, the amount of GI cement water sorption was more than Xenocem-plus resin cement. So according to the conditions and limitations of this study, the dimensional stability of Xenocem-plus cement is more than GI cement; Although has been explanted that water sorption can be a positive compensation factor.
